The problem is all the devices in the system have slightly different clock rates and that means you can't use any form of synchronous mode in the radio chip (because it is by definition asynchronous)
evofw3 on the ATMega328 does some very time critical edge measurements requiring at least a 16MHz MCU (in the avr family)
If there was a HW UART available I think you can just suck the message data out of the radio.
The key is being able to do byte synchronisation on the stop/start bit boundary.
A HW UART should be able to do this. All the SW UART implementations have to do edge analysis
